[Mk2] [Turbo] first run after HG fix etc, idles fine but go t pull away but stalls

[04kendalld]

all a bit odd mate, sounds like something not been put back together properly, vac lines etc... it's easy to do with a big job like the cylinder head. is the car showing boost when you drive it??

defo no boost pipes off lol, will check tomorow if he car is reading boost, i think it is could it be the £13 boost controller from ebay?

which is why im puting standard boost back on.

am jacking the car up and fitting hose clips to the ones that need it.

...I...what?

sorry haha tired.

im going to take off the £13 boost controller i got off ebay and put all the standard lines back in see if that makes a diffance to my boosting problem any ideas on my other issue?

[Ryan S]

yeah i'd deffo get rid of that first matey

if you want a manual boost controller, get one from GTS Chris. they never fail

[4ndee]

Is yours a bleed valve or a proper ball and spring boost controller?

i have run standard lines back on the turbo and reactivated fuek cut off so thats all back t standard, but the car is still boosting as soon as i put my foot on the accelerator ?

and still stop start syptoms

i have error codes

14 ignition signal, i have replaced plugs and leads and the car idles fine
24 intake air temp sensor, could anyone post a picture of where the sensor is and how its connected.
31 vacuum sensor, and again a pic of where this is ?


would any of theses codes make the car run bad etc

thanks for all help

i have error codes

And do they return if you reset the ECU?

IAT sensor is inside the AFM.
Vac. sensor (aka TPS), is on rear bulkhead next to diagnostic port.

All 3 codes could make car run bad.

Not in my workshop right now, but, IIRC, code 51 is related to IDL contact in TPS (throttle position sensor). Have you removed the TPS from the throttle bosy for any reason?

i didnt no but a friend removed the screws because he couldnt get the plug undo

Ahhh, now we get the full story.

There lies your problem.

The TPS needs to be set up carefully with a ohmeter. If you Google, you'll find the procedure.

i now have no fault codes

but my last issue is..

the car boosts to a point then holds back while spooling, with my foot planted it will eventually fulling boost ??

it fills like the TVIS system isnt opening, pressure builds until its forced open, probably not the reason but fills like it. i have put hose clamps on the hoses for the tvis so no leaks, have run standard lines for turbo/aculator down to the tvis, but its still not working.

can the tvis plate be put in the wrong way round, causing the boost to hold the flaps shut.

any help would be great.

sounds like a blocked CAT, you getting cat temp warning?? or do you have a decat??

EDIT: sounds like the symptoms i had with a blocked cat. cat temp warning light came on too.

i have a decatted 3" downpipe so cant be the cat, one sensor did break on the coolant neck, a white/grey plug could the be the cause of my issue, im pretty sure its the cold start injector switch.

so the tvis plate can only go on one way, so the pressure from the turbo wouldnt be stopping it opening ?

other ideas mate really want to get this sorted

any

[Ryan S]

hmmm, tvis is something i've no clue about at all i'm afraid mate, have a vague idea of what it does but that's it

sorry bit confused, any help on my issue would be great.

[Peter Gidden]

have run standard lines for turbo/aculator down to the tvis, but its still not working.

Please explain. There is no physical link between the turbo actuator and the T-VIS.

Everyone needs a clip

[bobhatton]

It sounds to me like your cam and ignition timing may well be out.
Can you please explain how you set them up
